Technical Description

The Ingersoll Rand SD-77DX is a heavy-duty, single-drum vibratory soil compactor designed for high-performance compaction of granular and cohesive soils. It features a 66-inch wide smooth steel drum with a 48-inch diameter, delivering a high centrifugal force of 32,148 lbs and a low setting of 23,380 lbs, with a nominal amplitude of 0.1 in at both settings. Vibration frequency is adjustable between 1,850 and 2,025 vpm (20.4–33.8 Hz), allowing optimal compaction across a range of soil types and lift thicknesses. The machine is powered by a Cummins B4.5T Tier 2 diesel engine, a turbocharged, inline 4-cylinder unit producing 99 hp (74 kW) net power, providing reliable performance and fuel efficiency in demanding applications. The SD-77DX has an operating weight of 16,350 lbs and an operating width of 74 inches, with a compact turning radius of 128 inches for excellent maneuverability on job sites. Overall dimensions include a length of 16.6 ft, width of 6.2 ft, and a cab height of 9.6 ft. It is equipped with 14.9x24 -6PR R3 tires, a 47.1-gallon fuel tank, and a 22.2-gallon hydraulic system fluid capacity. Standard features include a 12-volt electrical system with a 105-amp alternator and a maximum travel speed of 9.1 mph (14 km/h), making it a robust, efficient, and operator-friendly solution for road, utility, and site preparation work.
